Abstract: 본 발명은 유리섬유 보강 열경화성 복합재료의 제조방법에 관한 것으로서, 자동차의 차체 외판용 열경화성 수지 조성물을 종래 핸드 레이업(Hand Lay-Up) 제조공정을 통해 성형하였으나, 균일한 품질의 미확보와 변색의 문제가 있어 이를 배제하고, 대신에 저압 성형 SMC 제조공정을 이용하는 한편, 강도(strength)문제를 개선하기 위해 직조된 유리섬유 보강재를 적용하여 성형함으로써, 성형품의 강성 및 강도를 동시에 향상시킬 수 있을 뿐만 아니라, 내열성, 내수성 및 치수 안정성을 더욱 개선시킬 수 있는 유리섬유 보강 열경화성 복합재료의 제조방법에 관한 것이다.
